Maybe the main character could be a character from a sci - fi show, like Captain Kirk from Star Trek. After countless space adventures and dealing with alien threats, he takes a break to explore a more peaceful planet and interact with its inhabitants on a more personal level.
A character from a superhero universe, say Batman. He's always fighting crime in Gotham. In this fanfiction, he decides he needs a break from the constant vigilante work. He might go on a solo journey to find inner peace, away from the chaos of the city.
It could be about a character who has been through a lot, like a superhero constantly saving the world. They finally decide they need a break from all the chaos and responsibilities. Maybe they go to a secluded island or a peaceful countryside to unwind and rediscover themselves.
Vegeta could also be the main character. He has a strong pride and a burning desire to be the strongest. In a 'break through the limit' fanfic, his journey to surpass his own limits and perhaps even overtake Goku could make for an interesting story.
Bella could still be one of the main characters. She could be part of 'Operation Break the Dawn' as she already has a deep connection to the vampire and werewolf worlds. Another could be a new vampire created by an ancient ritual who has special powers. And Jacob might also play a major role, as he represents the werewolf side. He could be reluctant at first to be involved in the operation but then realizes its importance for the future of his pack and the Twilight world in general.
It could be an old wizard or witch in a magical world. Their virginity might be related to their magical powers. For instance, in some magical lore, virginity can be a source of great power, and this 107 - year - old character has harnessed that power throughout their long life.
The main character could be a young adult who is in a long - term relationship. He's at a point in his life where he wants more excitement and adventure, which he doesn't feel he's getting from his relationship with his girlfriend.
Obviously Naruto would be one of the main characters. There might also be his friends like Sasuke and Sakura. Kakashi could also be involved as his mentor.
It could be a young girl who discovers she has magical powers one day. Maybe she was an ordinary girl before, but then something extraordinary happens, like finding a magic amulet that unlocks her hidden powers.
It could be a new character introduced specifically for the fanfiction. This character could be someone who stumbles upon the world of lies and bodyguards by accident, like a curious journalist or a lost traveler. Their naivete or outsider perspective could drive the story forward as they try to make sense of it all.
It could also be a side character like Penny. If she gets damaged in a battle and is taken to the hospital for repairs. The story could focus on how the RWBY team reacts to her situation, and Penny's own thoughts as she is being fixed. Also, it could explore the relationship between Penny and the people in the hospital who are helping her.
A new character could be the main character in the HTTYD runaway fanfiction. For example, a young girl who has just become a dragon rider but is afraid of her new responsibilities. She runs away to avoid facing them, but during her time away, she bonds deeply with her dragon and gains the confidence to return and take on her duties.
